EXCLUSIVE: Penrith Mayor Greg Davies says "super councils" could work, but believes Penrith shouldn't have any grand plans to take over other council areas.
While the debate about whether or not there's too many levels of government is likely to continue for many years to come, Cr Davies said around 200,000 people is a good catchment for a council to have.
Penrith has around 185,000 residents living in the LGA.
"I'm loathed to use the term super councils because I think there's a physical limit where if you get too big you lose the value of local government," he said.
"However, having said that, do I think we should have councils around looking after 16,000 residents? No. In this day and age, it's very difficult to justify economically how you do that."
